Pomatostomus ruficeps

The chestnut-crowned babbler (Pomatostomus ruficeps) is a medium-sized bird that is endemic to arid and semi-arid areas of south-eastern Australia. It is a member of the family Pomatostomidae, which comprises five species of Australo-Papuan babblers. All are boisterous and highly social, living in groups of up to 23 individuals that forage and breed communally. Other names include red-capped babbler, rufous-crowned babbler and chatterer. Chestnut-crowned babblers are dark, brown-grey birds with a white throat and breast, white-tipped tail and a long, black, down-curved bill. Wings are short and rounded and the tail is long with a rounded tip. Diagnostic features include two white wing bars and a rich, chestnut crown highlighted by long, white eyebrows. The birds have dark brown eyes and grey legs, while the wings, back and flanks are brown-grey to mottled dusky on the mantle. The white of the throat and breast is well-defined and narrower than that of the similar, white-browed babbler (Pomatostomus superciliosus). Combined, these characteristics give the chestnut-crowned babbler a rather unusual appearance. At 21–23 cm and approximately 50 g in weight, the chestnut-crowned babbler is noticeably smaller than the grey-crowned babbler (Pomatostomus temporalis). It also gives the appearance of being slimmer than other babbler species. Adults are sexually monomorphic. Immature birds are like the adults but duller, with a pale rufous eyebrow and chest, brown crown and whitish patch behind the eye. Chestnut-crowned babblers are found in inland areas of south-eastern Australia, including parts of western New South Wales, south-western Queensland, eastern South Australia and north-western Victoria. Its distribution lies within the south-eastern Lake Eyre Basin and the western Murray-Darling Basin. The species commonly inhabits mallee, mulga and belar woodlands that are drier and more open than those occupied by the white-browed babbler and Hall's babbler (Pomatostomus halli). Other habitats include acacia and cypress pine scrubs and woodlands, stony ground and sandhills, and lignum, saltbush and samphire. Chestnut-crowned babblers are most readily sighted at Eulo Bore, Bowra Station and in Hattah-Kulkyne National Park, as well as along many outback roads including those between Quilpie and Windorah, and Bourke and Nyngan. Babblers are renowned for their cheerful, energetic, social behaviour. During the non-breeding season (December - June), chestnut-crowned babblers form cohesive social groups of 3 to 23 individuals that maintain a territory, roost and forage together. Dust-bathing and preening may also be undertaken as a group. At night, they crowd together in a communal roosting nest, built by the group in dead or partly living trees. These dormitory nests may also be disused breeding nests to which the group continues to add material. If disturbed, individuals hop away behind cover, departing in long, low glides. When alarmed, they may huddle together under dense foliage or dash up the under-canopy of trees and shrubs, chattering noisily. They are playful and have been known to wear trenches in the ground from chasing each other around; however, they are shyer than other babbler species.
